CARRIER FOR BRAIDING-MACHINES.

Specification of Letters Patent.

Patented Feb. 25, tom.

Application filed November 4, 1916. Serial No. 129,413.

To all whom it may concern:

Be it known that I, FRANK MossnERo, a citizen of the United States. and resident of the city of Attleboro, in the county of Bristol and State of lVlassachusetts, have invented certain new and useful Improvements in (arriers for Braiding-Machines, of which the following is a specification.

This invention relates to improvements in carriers for braiding machines and its primary object is to provide a carrier having a tension member acted upon by an extremely long and very yieldable coil spring thereby eliminating the ordinary gravity tension weight and producing a quicker acting more sensitive and reliable tension for controlling the yarn feed.

A further object of this invention 's to provide simple means whereby the operating tension of this spring may be readily adjusted.

My invention further consists in reducing the weight of the carrier over that of the ordinary construction and also the height of the operating parts, all of which features serve to permit an increase in its traveling speed without interfering with the operation of the let-off and without increasing the wear of the parts.

lVith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1-- is a side elevation of my improved carrier.

Fig. 2 is a rear view illustrating the shape of the guide eye formed in the standard.

Fig. 3- is a plan View showing the relative position of the spool spindle, the spring rod and the guide standard, all of which are mounted on the base.

Fig. 4:- is a perspective view of the spool controlling latch.

Fig. 5- is a modification showing a side elevation of the lower portion of a carrier with the latch formed to engage teeth on the periphery of one of the spool heads.

Referring to the drawings. designates the frame of the carrier having a groove 11 adapted to run and be guided in the usual race-Way of a braiding machine. said carrier being provided with a very short hub 12 having the usual spindle 13 on which is mounted the yarn spool 14 which may be provided with the usual ratchet teeth 15 preferably in this case formed on its lower end. In order to engage these ratchet teeth and so control the rotation of the spoolfa pawl 16 is pivotally mounted at 17 on the hub 12' to extend forward and this pawl is provided with a tooth 18 adapted to engage those of the spool. A spring 19 is provided for normally holding the pawl tooth in engagement with the spool, the opposite end of this pawl is provided with an eye 20 to receive a connector 21 presently described.

One of the features of my invention is the provision of a yarn guide standard 22, the same being preferably constructed of a length of wire bent at its: middle portion into an open coil as at 23 to provide a guide eye through which the yarn a may be threaded, this open coil being for the purpose of permitting the bight of the yarn to'be passed thereinto without being obliged to thread the end through the eye, said coil providing what is known as a self-threading eye.

The upper end of this standard is also provided with an open coil 24 to provide an upper guide eye for the yarn, the axis of this coil 'being preferably substantially parallel with that of the axis of the standard. and this coil is also of the self-threading type.

The lower end of this guide wire 22 is preferably reduced and riveted into the holes 26 in the frame of the carrier.

Another feature of this invention is the provision of a separate and independent rod or spindle with its lower end riveted into the frame as at 27 and extending upward nearly the length of the guide standard 22. This rod is preferably threaded from its top downward nearly one-half its length and this threaded portion is shown as being provided with a. nut 27 which is split as at 28 to form a spring binding nut adapted to grip the threads and prevent unscrewing even when acted upon by thevibration of the moving parts.

A very light and long helical spring 29 is mounted on this spindle, its lower end pressing upon a tension sleeve 30, which sleeve is mounted to slide freely endwise on this rod and is provided with a bifurcated arm 31 extending out. and around the standard 22 and is also provided with an arm 32 having an eye 33 through which the yarn a is threaded.

This arm is for the purpose of engaging the loop 34 of the connector 21 passed around the standard 22 whereby when suflicient tension is applied to the yarn to raise this tension high enough to engage the connector, this action of this tension member moves the latch to release thespool and permit more yarn to be unwound therefrom.

I have shown and described the nut 27 as being split but any means may be employed for locking this nut in any desired position against its accidental movement due to vibration while running.

By my improved construction of providing a spring of great length which renders it extremely soft and yieldable, the tension member is caused to work veryquickly and not depend upon gravity for its action, which is the case with the usual bottom weight, which when running at a high rate of speed is acted upon by centrifugal force which prevents quick action and interferes with the practical operation .of the machine.

Then again by eliminating the usual heavy guide standard and supplying a standard formed of wire, I obtain two advantages; first, I materially reduce the weight of the carrier; and second, I am enabled to bend the wire into eyes to afford most practical guides for the yarn.

The whole construction of my improved carrier is particularly light in weight, inexpensive to manufacture and practical and effective in its operation.

Having thus described one illustrative embodiment of my invention I desire it to beunderstood that although specific terms are employed they are used in a generic and descriptive sense and not for the purpose of limitation, the scope of the invention being defined and limited only by the appended claims.

I claim:

1. A carrier for braiding machines comprising a spool supportingbase, a vertical spool spindle on said base, a yarn guide standard, an independent spring carrying standard of a height at least that of said spool spindle, a compression coil spring en circling said spring standard for substantially its length, a spring pressed tension member slidably mounted on said spring standard and also having a sliding engagement with said guide standard, and a latch for the spool, said latch having a connector engaging said guide standard and positioned to be engaged by the tension member when raised to a predetermined height by the tension of the yarn.

2. A carrier for braiding machines comprising a spool supporting base, a vertical spool spindle on said base, a yarn guide standard, an independent spring carryin standard of a height at least that of said spool spindle, a compression coil spring en- 'circling said spring standard a spring tension member slidably mounted on said spring standard and also having a sliding engagement with said guide standard, a latch aving a connector engaging said guide standard and positioned to be engaged by the tension member when raised to a predetermined height by the tension of the yarn, and means on said spring standard whereby the tension of its spring may be readily adjusted.

3. A carrier for braiding machines comprising a spool-supporting base, a yarn guide standard, a spring carrying spindle, a spring-pressed tension member slidably mounted on said spindle and provided with a radially disposed arm having sliding engagement with said standard, a latch for the spool having a connector engaging said guide standard and positioned to be engaged by said arm when raised a predetermined height by the tension of the arm, said tension member also having a second radially disposed arm arranged at an angle with respect to the first mentioned arm and having an eye to receive the arm.
